I need to put in a mask in field rules for a phone number field. The field is C 15 because I need to put in a 1 if the number will require a 1 to dial correctly. I am using the following mask in field rules:

0(000) 000-0000

This field on a form, when in change mode looks as follows:

1(222) |33-3-44

This is weird. Anyone know why it would do this?
It will save correctly but the display is wrong. If I can't fix it I will have to do it with a separate field.

TIA
